WHEEL.

SPECIFICATION forming part of Letters Patent No. 651,086, dated J' une5, 1900.

Applicationtlled September I9, 1899. Serial No. 730,992. (No model.)

To LZZ whom, it may concern:

Be it known that I, FERNANDO PROTHERO, a citizen of the United States,residing at Michigan Bar, in the county of Sacramento and State ofCalifornia, have invented certain new and useful Improvements in Wheels;and I dodeclare the following to be a full, clear, and eX- actdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

My invention relates to that class of wheels which are adapted to beadjusted, with a view of taking up looseness and tightening their tires.

It consists in the strong and durable and otherwise advantageousconstruction hereinafter described, and particularly pointed out in theclaim appended.

In the anrexed drawings, Figure l is a lon'- gitudinal sectional view ofthe hub and felly of my improved wheel. Fig. 2 is a section taken in theplane indicated by the broken line 2 2 of Fig. I. Fig. 3 is a detachedview of the joining ends of the felly, showing the clip thereon insection. Fig. 4 is a detail perspective view of the hub-body 5 of theimproved wheel.

Similar letters and figures of reference indicate corresponding parts inthe several views.

l designates an axletree provided with a spindle 2, of the usual formand function. On the inner end of the spindle 2 a collar 3 is rigidlyXed. The free end of said spindle 2 is fitted with screw-threads and hasa nut 4 inserted thereon.

The hub of my wheel is formed of the cylindrical body 5, which isadapted to receive a box 7 within the same. The rear or inner end 6 ofsaid body 5 is enlarged, as shown in cross-section, Fig. I, and providedat suitable intervals on the periphery thereof with apertures 8 for thereception of the ends of spokes 9. The outer end portion of the body 5is exteriorly of rectangular form in cross-section and is provided withthe alternate dat faces ct and rounded and threaded corners b, as bestshown in Fig. 4. The flat faces a of the hub-body are design ed for theengagement of the adjustable sleeve or section l0, which has a squarebore, while the rounded and threaded corners b are designed for theengagement of a nut l1, through the medium of which the sleeve IO isadjusted and adjustably fixed. The sleeve IO has spoke-receivingapertures 8 in its periphery and is designed to be adj usted, as

to securely retain the spokes in their proper relative positions. A n utl l, of suitable shape and size, having screw-threads cut interiorlytherein, is inserted over the outer end of the hub 5 6 and adapted tobear against the outer side of the sleeve IO. A lock-nut 12, which mayhave an ornamental closed end 13, may be placed over the extreme end ofthe hub 5 G, so as to bear against the nut Il for the purpose ofmaintaining the same in rigid position. A felly I4, having any suitabletire I5, may be placed in position over the free ends of the spokes 9.The abutting ends of the felly 14 are secured in position by a clip 16of ordinary external appearance, having a Wedge-shaped lug 17 rigidlyattached on the inner surface thereof. The lug I7 is adapted to enterbetween the ends of the said felly 14 for the purpose of carrying apiece of leather I8 or other suitable material, which is adapted to tillthe space between the 'ends of said felly when the same is pressed outagainst the tire, as herein described. The

lug 17 is adapted to be driven into place and the clip I6 attached inposition by bolts 19, which may be inserted through slots in said clipI6.

The mode of operating my improved wheel is as follows: The box 7 isplaced in the hub outer ends thereof being engaged by a suit- IDO ablefelly 14, which is encompassed by a tire 15, of suitable material. Thenut l1 is then placed in position over the end of the body 5 and againstthe sleeve 10, upon which said nut is adapted to bear, pressing the samein Wardly, which, as will be seen, presses the spokes 9 outwardlyagainst the felly 14, causing the wheel to become extremely tight inevery part. After the nut ll has been impelled against the sleeve 10until all parts are tight the lock or jam-nut 12 is introduced over theend of the hub and engaged with the nut 11 for the purpose ofmaintaining the same in rigid position.

When applied to the axle; the operation is as in ordinary cases. The nut12 13 is removed, the nut 4 placed on the end of the spindle 2, and thenut 12 13 replaced.

lVhen the tire becomes loose from any cause, the nut 12 13 may beremoved and the nut l1 impelled against the sleeve 10 until the tire istight. The nut 12 13 may then be placed in position against said nut 11.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination of an axle-spindle having a threaded outer end, a nutmounted on said end of the spindle, a Wheel comprising the hub-bodyarranged on the spindle, and having` the enlargement G at its inner endprovided with spoke-sockets, and also having the outer portion ofangular form in cross-section provided with alternate flat faces cr androunded and threaded corners b, the sleeve 10, having the rectangularbore, arranged and adapted to slide on the rectangular outer portion ofthe body, and having spoke-sockets in its periphery, and a nut arrangedon the outer end of the hub-body 5 and engaging the threaded cornersthereof,substantiall y as and for the purpose set forth.

In testimony whereof I aiiix my signature in presence of two witnesses.
